QXRtueoM/a EDGAR A. MILLS, OF BALTEIOBE, AND RICHARD H. RICHARDS, 0FHAMILTON, MARYLAND, ASSIGNOBS OF THREE-FIFTHS TO JOHN B. WELLS, 0FBALTIMORE,

WATER-HEATER- Application filed January 18, 1915. Serial No. 2,941.

To all whom, it may concern:

Be it known that we,EneAn A. Mum and RIOHARL H. RICHARDS, citizens ofthe United States, residing at Baltimore and Hamilton, respectively, inthe county of Baltimore and State of Maryland, have invented certain newand useful Improvements in Water- Heaters; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to improvements in water heaters, andconsists of a certain novel construction hereinafter described andclaimed.

It is an object of the present invention to provide an improved waterheater which will be constructed to aiford a relatively increased areaand exposure to the flame of the burner, whereby the heater will be forall purposes instantaneous in action and will heat the water to a highdegree in a minimum space of time.

A further object of the present invention resides in providing animproved water heater, the construction whereofwill be simple and thecost of manufacture economical; and the same will be arranged to bedetachably connected with any of the approved forms of gas or otherburners found on the modern types of stoves. I

With these and other objects in view the invention consists in the noveldetails of construction and combinations of parts more fully hereinafterdisclosed and particularly pointed out in the claim.

In the accompanying drawings forming a part of this application, and inwhich similar reference symbols indicate corresponding parts in theseveral views, Figure l is a plan view showingthe heater and burner 1noperative position; Fig. 2 shows a side elevation of the device shown inFig. 1, parts being broken away; Fig. 3 is a bottom plan view,'partly insection, of a water heater constructed in accordance with the presentinvention. Fig. 4. is a cross sectional view taken on the line 2-2 ofFig. 3, and looking in the direction of the arrows; and Fig. 5 is asimilar view taken on the line 33 of Fig. 3, and looking in thedirection of the arrows.

In Figs. 1 and 2 the heater is shown in plan or in the upright position,while in Figs. 3, 4 and 5 the heater is shown inverted.

Referring more particularly to the drawmgs, the improved water heater isconstructed of a casting arranged to provide an annular water chamber 1,comprised between an annular upper wall 2, disposed horizontally, and apair of inclined walls 3 and 4, connected at their upper ends toopposite ends of the horizontal wall 2, and united at their lower endsin V relation.

The outer edge of the horizontal wall 2, as likewise the upper edge ofthe inclined wall 4., is arranged scalloped, as shown at 15, so as toprovide a uniform wall area throughout the heater, and to increase theconducting and radiating surface thereof.

As advantageously disclosed in Figs. 1 and 3, the heater is constructedwith a plurality of inwardly and radially disposed hollow projectionsarranged in communication with the annular channel 1, and formed bysubstantially triangular extensions 5 of the horizontal annular wall 2,and pairs of inclined-walls 6 and 7 united to the opposite edges of theextensions 5, and merging in'golthe annular inclined wall 3 of thechanne The inclined walls 6 and 7 of each of the radially disposedprojections provide therebetween ridges 8, which are encountered by theflame of the burner and separate and direct the flame to either sidethereof and against the faces of the walls. The outer inclined andannular wall 4 is preferably formed, opposite each .of the inwardlydisposed projections, with a bafiie plate 9, extending centrally betweenthe walls of the projections and terminating short of the inner endsthereof, whereby to provide a zigzag or tortuous channel for the wateras the same passes through the heater.

The water may be introduced through one connection 10, as shown in Figs.land 3, and passes out from the heater through a connection 11, arrangedadjacent to the connection 10 and separated therefrom by a wall 12extending between the annular walls of the channel 1.

Any suitable burner may be used, such, for instance, as the stellatedburner B having radial arms B, shown in Figs. 1 and 2, but the burnernot being a part of our invention will not be further described.

Patented June 22, 1915. i

To facilitate positioning and centering of the heater upon the burner,the same is preferably formed with depressions 13, as more particularlyseen in Fig. l, which are adapted to be received by the framework of theburner or stove and support the heater at the desired position.

It will be understood from the foregoing description, taken inconnection with the drawings, that the improved heater is constructed toprovide Walls of substantially uniform width throughout, and to afiord arelatively increased surface exposure to the flame of the burner wherebythe heater will be practically instantaneous in effect. The heater maybe connected inany suitable manner to any approved type of stand boiler,or other circulating means, and

readily disconnected therefrom and replaced, and such heater is adaptedto cooperate with any of the types of burners or stoves now in use. Thecirculation of the water through the heater will be in one directionthrough the annular channel 1,

and will be compelled by the baflles 9 to enter the radial projectionssuccessively until exhausted through the connection 11.

It is obvious that those skilled in the art may vary the details ofconstruction and arrangements of parts without departing from the spiritofour invention, and therefore We do not Wish to be limited to suchfeatures expect as may required by the'claim.

side of said radial partition, the exterior of said body portion beingscalloped to provide an increased heat absorbing and transmittingsurface, and the interior of said body portion being provided with aseries of hollow radial legs terminating at a distance from the centerof said body portion so as to leave a substantially annular openingtherethrough, which legs are V-shaped in cross section, being providedwith downwardlyinclined side walls, and being also provided withinclined V-shaped end walls, and the bottom of said legs sloping upwardtoward the center of said body portion, substantially as described.

In testimony whereof, we aflix our signatures, in presence of twowitnesses.
